YARN-CLEARER OR SLUB-CATGHER.

To all whom it may concern:

Be it known that I, GEORGE HLL ARTH Fos'rnn, a citizen of the United States, resid ing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Yarn-Clearers or Slub-Gatchers, of which the following is a specification. Y Y

My invention relates toslubbingdevices and consists in a slubbing device having two members, one rounded and the other a blade," ad ustable in respect to each other, as fully set forth hereinafter and as illustrated in the accompanying drawing, in which Figure 1 is a side View of my improved 'slubbing device; Fig. 2, an end vew; and- Fig. 3, a cross section illustrating the 'arrangement in respect to a cop'in a slubbing machine. p

The device consistsessentiallyof a'smooth practically cylindrical member 1 or jaw and a parallel blade or blade-shaped jaw B preferably having a sharpened or beveled edge a with means for adjusting the blade to different positionsabout the member ,A,

while maintaining it at all times parallel thereto, and means for adjusting one member or the other so as to increase or decrease the distance between the two so that a thread which is carried between the members and resting upon the smooth surface of the member A will have any slubs or enlargements removed by contact with'the edge of the member B. These parts may be constructed and arranged so as to secure the necessary relations and adjustments in difl'erent ways. As shown, the member A is' a cylinder of any suitable material with a smooth surface. It may be of metal, but preferably it is of glass or porcelain and has an eccentric openin}; receiving the stud D connected to any suitable support E, and the blade B is carried by the arm 2 of a sleeve or bushing F, which is socketed to receive the end of the stud D, and which may be secured in any suitable position thereon by means of a set The arm, 2 has a socket y to receive one end of the blade B, which preferably is pressed into the socket by a spring 5 encircling the bushing F. r

The sleeve or bushing F constitutes a head which supports the knife or blade member B in fixed relation to the eccentric roller member A, thehlatter being shown Specification of Letters Patent.

positioned above the knife upon the stud .D, which is secured to the head.

A spring 6 encircling the stud D and bearing against the support E and the adjacent endof themember A forces the lat-.

ter longitudinallyagainst a washer 7, bearing on the bushing F. I

The parts being thus arranged, the spring 6' exerts su'flicient. force to hold the eccentrically pivoted roller or member A in frictional contact with the washer 7, so that the member Azwill not turn under the operations in slubbing, but the operator can readily graspgthe end of the member A beyond the." blade B and turn-the said member so as to increase the distance between it and ating upon threads ofdiiferent thicknesses and characters; It will thus be seen that the spring fi constitutes means for retaining A o the roller or member A in spaced relation with-the-knife or blade B.

Of course, the blade B might be ad ustable to and from the member A, but in any event the face of the member A and the edge of .the blade B are always equidistant and the bladeB, as may be required when opcr parallel so that the thread is properly operated upon, I consequence of the length of the members A, B, the

from one position to the other, and thus avoid grooving the face of the member A while the roundvsmooth surface of the memher A permits the yarn to pass at any angle to the clearer without abrasion. As the bushing F is rotatably adjustable upon the to be set at any desired position radially. The adwhich it will be seen that if the thread is carried to the slubbing device along any of the dotted lines, shown in said figure, the blade B can always be arranged substan tially at right angles to the line of feed of the thread or yarn, so that the latter will take its bearing on the member A, and will not be drawn across the edge of the member B.

Whilethe member B ma be secured rigidly to the bushing), I pre er to hold it in contact therewith y a spring so that the o erator, by pressing on the end of the b ade, may clean the parts from flock, and the blade will then resume its proper-position in relation to the member A.

thread can 'move back and forth whatever its position, and in blade-shaped Without limiting myself to the construction and arrangement of parts shown, I claim:

1. The combination in a slubbing device of a stud upon a fixed support, a cylinder A having an eccentric opening receiving said stud, means for holding the cylinder frictionally upon the stud, and a member B having a beveled edge and supported radially in respect to the cylinder with its sharp edge adjacent thereto.

2. The combination of a stud, a member A knife, substantially as described.

5. In a device for the purpose set forth, in combination, a suitable head or support, a blade-shaped jaw mounted on said support, a rotatable eccentrically-mounted jaw arranged on said support parallel with the jaw, and means for holding the rotatable aw at any point of rotation, whereby the width of the opening between being constructed topresent in its various adjustments curved surfaces to the thread passing between the jaws.

6. In a device for the purpose set forth, in combination, a suitable support, a bladeshaped jaw mounted on said support, a cylindrical rotatable eccentrically-mounted jaw arranged parallel with the blade-shaped jaw, and means for holding the ec'centrically mounted jaw at any point of its rotation, whereby the width of the slit between the jaws is adjusted.

7. In a device for the purpose set forth, in combination, a suitable support, a cylindrical rotatable eccentrically mounted jaw carried by said support, a parallel bladeshaped jaw also carried by said support, and means for holding the rotatable jaw in any desired position, the blade-shaped jaw being movably connected to the support.

8. In a device for the purpose set forth, in combination, a suitable support, a cylindrical rotatable eccentrically mounted jaw, and a blade-shaped jaw coacting there-with, said jaws bein relatively adjustable on said support where y the wldth of the slit between the jaws is adjusted.

In testimony whereof I aflix my signature in presence 0 two witnesses.
